摘要： A proximity sensor system includes a sensor matrix array having a characteristic capacitance on horizontal and vertical conductors connected to sensor pads. The capacitance changes as a function of the proximity of an object or objects to the sensor matrix. The change in capacitance of each node in both the X and Y directions of the matrix due to the approach of an object is converted to a set of voltages in the X and Y directions. These voltages are processed by digital circuitry to develop electrical signals representative of the centroid of the profile of the object, i.e, its position in the X and Y dimensions. Noise reduction and background level setting techniques inherently available in the architecture are employed.

摘要： A clock recovery circuit includes a phase detector, a loop filter, a phase rotator, a predictor and a delay line. The phase detector receives an input data signal and generates a phase error signal for estimating phase error in the input data signal when referred to a recovered clock. The loop filter receives the phase error signal and determines a phase control signal based on the phase error signal. The phase rotator receives the phase control signal, and provides a phase adjusted clock based on a reference clock and the phase control signal. The predictor receives the phase error signal, and determines a delay control signal based on the phase error signal. The delay line outputs the recovered clock by delaying the phase adjusted clock from the phase rotator using the delay control signal from the predictor, and provides the recovered clock to the phase detector.

摘要： A sliver compactor is provided between a drafting roller of a drafting frame and the delivery unit which supplies the sliver to the spinning stations of the spinning machine. The sliver compactor has a shielding element juxtaposed with the perforated moving surface to which suction is applied and which reduces the suction force required to draw the fibers of the sliver into a compact form. The shielding element extends over a plurality of slivers and the respective spinning stations and a number of such shielding elements may be aligned over the length of the machine below the stretching field plane and secured on the machine frame.
